They are $3K new with the latest and greatest internals from Tremec. That is the T56 Magnum with wider gear faces, larger bearings to handle more load, everything inside is made of a better steel, 31 spline output shaft, the case is 2-3lbs heavier casting (less deflection), triple synchros (better shifting), electronic and mechanic speedo outputs, and a provision for transmission cooler bungs if you were to seriously endurance race with it.
I have one in my Chevelle and FD RX-7. Worth the $$$.
